The total mechanical energy of an object with mass m at height h in a closed system can be written as . Solve for v, the velocity of the object, in terms of the given quantities. v =

Step-by-step explanation:

Total energy-k.e+p.e

M.E-P.E=K.E

Now,

Now,Solving for velocity

V² =2(M.E-P.E)/m

Therefore,

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
